...s->mirror_fault_exclusion_lock); } All that is needed is to make sure that vm_normal_page() will see those pte (inside the process that is mirroring the other process) as special which is the case either because insert_pfn() mark the pte as special or the kvm device driver which control the vm_operation struct set a find_special_page() callback that always return NULL, or the vma has either VM_PFNMAP or VM_MIXEDMAP set (which is the case with insert_pfn). So you can keep the existing kvm code unmodified. Cheers, J?r?me

Hi folks, we use meetme application with pin so when a customer joins he's prompted for his name. Then the voice say:"press one to accept the recording..." My question is, is it possible to cut off that request to"press one"? Thanks to all -- .:FaberK:.
